Question

Le Châtelier's principle states that if a stress is applied to a system at equilibrium, the system will shift to relieve that stress. This is true for all types of equilibrium, including the dissolution of salts that are only sparingly soluble.

Here is the chemical reaction that represents solid silver bromide dissolving in water:

Part A

Which of the following actions would shift this reaction toward solid silver bromide?

Which of the following actions would shift this reaction toward solid silver bromide?

=5.3×1013

AgBr(s) Ag+(aq)+Br(aq) Ksp

Part A

Which of the following actions would shift this reaction toward solid silver bromide?

Which of the following actions would shift this reaction toward solid silver bromide?

Add more silver bromide. Add more bromide ions. Remove bromide ions. Remove silver ions.

=5.3×1013

Explanation / Answer

AgBr(s) Ag+(aq) + Br(aq)

Add more bromide ions.

By the addition of more bromide ions to the solution, bromide ion concentration increased on right side. But according to LeChatlier's principle, equilibrium shifts in the direction of decreasing the concentration of bromide ions i.e. backward direction. In other word that is towards solid silver bromide.

Add more silver bromide, Remove bromide ions and Remove silver ions.All these actions will shift the equilibrium in forward direction.
